Requirement Gathering or commonly known as the Discovery Phase is basically a process in which we understand and identify a business’s project technical requirements and proceed with a well-defined plan.
Although the discovery phase is an essential phase in any critical project plan, it is quite often overlooked with the absence of sufficient ground work.
Some of the project managers/consultants might argue that if a client’s requirements are accurately identified in the early stages, then completing a full phase of requirements gathering is simply not needed. One can actually not stress enough on the importance of discovery phase.
If the requirement gathering is not done properly, it can result into project deliverables not meeting the business requirements which in turn would result in waste of time and money.

This phase is critical as the information gathered will be utilized as a base for the System Requirements Specifications (SRS) document.
The SRS will include a vision or mission statement of the client company defining the overall objectives and business plans.
So basically, requirements gathering phase enables both the parties to minimize risks and balance the task management within the required timeframe. A process of discovery phase must always include key executives and stakeholders.
Techniques for Requirements Gathering
An ideal business analyst must follow some techniques for the requirements gathering process. Some of them have been discussed briefly below.
Interview turns out to be one of the most effective techniques for requirement gathering. In this method, the business analyst talks to the user and clients who are unable to give out detailed information as they are not aware of the system development and related functionalities.
It is the responsibility of the business analyst to extract relevant information from them which can be achieved by interview.
Survey is another effective method to collect information and requirements within a short frame of time. Under this technique, it is advisable to first ascertain the goal of the survey and thereafter draft the questionnaire.
Once your questions list is ready, it should be delivered to the user as well as the stakeholder for answers. A responsible business analyst would study the answers and then document them.
SMEs or subject matter experts are the responsible people to conduct brainstorming sessions. They discuss and find out solutions to complex issues.
They are further responsible for requirement prioritization post they collect all the requirements which are related to the software.
#4 Joint Application Method
This method follows a prototyping method, under which all the stakeholders like developers, end users, SMEs, business analysts and software engineers come together and attend workshops for working on a system in greater detail.
These stakeholders attend the workshops till the time the desired goal is accomplished.
Under the observation method, the responsible person observes the team in working environment and gets ideas about the software and subsequently document the observation.
Observation can be invisible, the person simply observes the working and does not interact or makes himself visible, and hence, the concerned person observes and asks relevant questions.
#6 Focus Group
In this method, the business analyst bases his/her requirement gathering process by interacting with the representative of the client and users.
The representative here has a broad idea pertaining to the needs of the users and clients. Under focus group, the idea is to collect information from representatives to understand the software idea clearly.
#7 Interface Analysis
Interface analysis is a specialized technique in which specific requirements related to application development are determined and their interaction with other software components is measured.
This is a technique of building a model of software which helps in uncovering and capturing software requirements from client. The output can be broad mockups or sketch formats of software.
#9 Use case diagram
Use case diagram is a technique that shows how people interact with software. It shows what a system does.
#10 Problem Reports and Suggestion Analysis
Requirements analysis can also be done from change suggestions and user issues. A direct method to look for requirements is to see the suggestions and problems that are described in the document first.
Some organizations have forms to report and record system problems; one can look through such a report and sort the problems into some key areas that are troubling the client.
The users can be asked questions on these to clarify doubts of the users.
When you want to select which technique to apply, there are a few factors that need to be considered:
- Availability and location of the stakeholders
- Client and development team’s knowledge on the problem
- Client and development team’s knowledge of the development process and methods to resolve the same.
Reduce Risk in Requirements Gathering
Gathering and managing requirements is a challenge in effective project management. It can be a matter of success or failure for projects if the requirement gathering is ineffective and this can happen even if the project is midway.
Web projects have a baseline that is continuously evolving throughout the timeline of the project which needs careful and effectual management.
The project manager needs to duly assess and understand the novelty value of the requirement gathering process of individual project.
Requirement risks are one of the most insidious risks that threaten IT project and their effectual management.
Having unclear requirements, lack of client involvement in the requirement gathering process or faulty requirements; all these become the major perpetrators in the projects which are likely to go awry.
Following agile practices can effectively help you in mitigating such risks to a large extent.
Project teams can make a lot of difference by adopting and executing agile working practices. If implemented accurately, agile working can reduce the risks that are associated with requirements gathering in IT projects.

Overcoming Challenges in Requirements Gathering
Soliciting and collecting business requirements is a critical step for any kind of project. Creating complete set of requirements at a preliminary stage can facilitates in better planning, precise cost estimates, shorter delivery timeline, enhanced client satisfaction and better response to the final product.
Eliminating the gap between business and technical requirements is the responsibility of business analysts as they need to understand the business needs in the full context and align the same with the business objectives while communicating the same to the development team as well as other company stakeholders.
For the said purpose, they need to ensure that the requirements are written in a form that is easily understandable by both the groups.
Business analysts also need to stir between vague and sometimes differing views of the stakeholders in order to concur on what needs to be accomplished.
There are times when the requirements gathering efforts are hindered by several kinds of pitfalls. Herein we shall discuss about the various challenges that can grip the requirements gathering process and discuss the potential approaches to deal with them.
#1 Lack of Clarity in Defining Criteria for Success
Stakeholders and usually clients have a clear idea about the problems they are facing or exploring a particular opportunity; however, more often than not they are pretty clueless about exactly what they are looking to achieve.
In order to address this concern, it is advisable to break the project into small bits and start from the section where the client has most clarity.
There are collaborative modelling tools which allow the clients to have a high level vision of the end result which makes getting feedback early in the process simple enough.
It is also advisable to ask questions from the client and identify current business practices and identify the pain points which can be improvised.
In any case, the best thing to do is make the requirements quantifiable and testable so as to have a solid foundation against which the results can be later measured.
#2 Clients Change their Minds Often
When the requirements are not clearly defined or understood/evolved over the course of the project, changes are bound to happen.
The best approach to tackle it is to become adaptable and accept the changes. Although, it is important that the changes are prioritized and estimated and new time and budget allocations are communicated and confirmed with the client before modifications are taken care of.
#3 Lack of or Over Communication by Clients
Active communication and participation by clients and stakeholders is critical to the success of the requirement gathering process. Getting the stakeholders to provide honest and open inputs requires establishing a rapport of trust.
It is important to listen, learn and speak the client’s language for their project and the same implies that you are interested as well as have understood the client’s business challenges and are here to focus on resolving the issues.
#4 Clients get Finicky over certain Techniques/Solutions
Clients often get too stuck up on a particular technology or software which happens when they have limited knowledge in certain technical areas or when a particular technology has worked wonders for them in the past.
The best thing to do here is to try and divert the client’s attention towards the main focal point i.e. how the problem will be resolved and ask them whether their choice of technology can play any significant role in the present scenario.
#5 Stakeholders can have Conflicting Priorities
Requirements gathering process needs to have a tough approach which includes asking open ended questions for the stakeholders to answer.
All stakeholders involved must articulate their ideas and perspectives in a timely manner. Rushing through process may lead to proposed terms that are considered out of scope, or promoting individual agendas rather than the organization’s vision.
A desirable thing to do is to have several interactive sessions with the client that has enough scope in between to digest the inputs collected, ensuring that the requirements gathering process gets on the right track delivering the right results.
At NMG, we set up a dedicated business analyst whose job is to understand your business requirement and accordingly conduct a series of brainstorming sessions in order to correctly identify your business model and understand your thought process, functional requirement, target audience and competition etc.
Based on the brainstorming sessions, the business analyst will then analyze the requirements and draft an SRS (system requirement specification) document.
This document would include basic objectives, functional as well as data description, system architecture, ACD (architecture context diagram), systems requirements and some suggested additional revenue streams and also the basic USP (unique selling point) of your web application etc.
We also set up a creative designer who will be working on the design elements of a website and design all the unique screens of the website.
Post the designs of the screens are made, we shall HTMLise them duly to converted to prototype. The estimate given is for about 10-15 unique pages. Once this phase gets over, you will get a clear roadmap along with correct time, team and cost estimate.
In further detail an SRS document prepared by NMG, will include the following component details:
- The document will be drafted by the business analyst.
- The document will be submitted in a MS Word document or PDF format.
- The SRS will include some further details as follows:
- Project Overview
- Objectives & Constraints
- Functional and data Description
- System architecture
- Architecture context diagram (ACD)
- System module narrative
- Resource requirements
- Team members by skill type
- Systems requirements
- Estimates will further include the following:
- Development timeline based on above
- Costs associated with each element above
- Hosting Requirements, Cost Estimation, TimeLine
In the industry having multiple companies vying for the top slot, there are a few best practices in the requirements gathering phase that must be followed for most desirable results.
Requirements Gathering Best Practices
#1 The primary important step in requirement gathering phase is identifying the problem along with the business users and defining in the most accurate manner. This definition must include:
- Project issue and the advised solution
- What are the benefits that are expected from this solution
#2 Accurate and detailed description of the project. The solution that has been planned should be adequately described at a high level along with the business requirements that it is centered on.
#3 It is imperative to address all the needs of stakeholders as well as users. This is a relevant part of requirements analysis and an important step which we should follow methodically before we freeze the requirements. This step helps in the deployment phase as well since the user gets adaptable to the new process/application.
#4 The solution offered must have its set of do’s and don’ts which should be captured in detail. This will be helpful in clarifying any doubts.
#5 The application should have its planned features captured in grave detail. The functional, as well as non-functional requirements should also be captured in much detail further including details on the project’s execution strategy.
To be successful in requirements gathering or discovery phase, it is vital that the business analyst draws out a plan which is helpful for capturing the basic requirements of the client. When this plan is carefully researched and drafted, there is little room for rework which further helps in saving time.
It is also necessary that all the stakeholders give their view with regard to the software being developed and kept in loop of the progress being made.
Working as per the requirement gathering process ensures that the quality of the end product is superlative and makes it simpler at all stages of the SDLC.
This phase gives a solid foundation to the rest of the processes and steps for design and development and hence ensures that the problem is resolved.
The stronger the foundation and clearer the understanding for the project, smoother will be the course of things when development begins and we move onto the support and testing phases of the project.
There might be a time when getting the perfect requirements gets difficult; however, better the understanding, more solid the end product would turn out to be.
This document is your trigger point for designing, documenting and developing and will be of immense help in all aspects of the project some time or the other.
